Sean had $82, Ethan had $34 and David had five times the total amount of money Sean and Ethan had. How much must David give to Sean and Ethan so that each of them has an equal amount of money?
- Sean
- Ethan
(a)
Total amount that Sean and Ethan had
= 82 + 34
= $116
Amount that David had
= 5 x 116
= $580
Total amount that the 3 boys had
= 116 + 580
= $696
Amount that each of them must have so that each of them has an equal amount of money
= 696 ÷ 3
= $232
Amount that David must give to Sean
= 232 - 82
= $150
(b)
Amount that David must give to Ethan
= 232 - 34
= $198
Answer(s): (a) $150; (b) $198
